2130-AC09 201110 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2130 Federal Railroad Administration FRA 2100 Department of Transportation DOT Vehicle/Track Interaction Safety Standards; High-Speed and High Cant Deficiency Operations This rulemaking would amend the Track Safety Standards and Passenger Equipment Safety Standards for high-speed train operations and train operations at high cant deficiencies to promote the safe interaction of rail vehicles with the track over which they operate. It would revise both the safety limits for these operations and the process to qualify them. It accounts for a range of vehicle types that are currently used and may likely be used on future high-speed or high cant deficiency rail operations, and would provide safety assurance for train operations in all classes of track. It is based on the results of simulation studies designed to identify track geometry irregularities associated with unsafe wheel forces and acceleration, thorough reviews of vehicle qualification and revenue service test data, and consideration of international practices.
